Recently, the first domestic high manganese steel marine fuel tank manufactured by HBIS Group Wugang Company high manganese steel ran well on the "GasChem Phoenix" ship, helping the ship to run safely for more than 20,000 nautical miles. The high manganese steel produced by Wugang was the first to be applied on board in China, marking the leap from basic material research to domestic engineering application of a new generation of low-cost, high-performance, ultra-low-temperature domestic high manganese steel, which is a milestone in the promotion and application of high manganese steel.
High manganese steel is a pure austenitic alloy steel with a manganese content of 22% to 25% and no nickel. It has good low-temperature toughness, high ductility and high strength. Compared with the traditional LNG tank manufacturing material Ni-based low-temperature steel, it has more obvious economic benefits and helps companies reduce production costs and improve market competitiveness.
Wugang is market- and customer-oriented, giving full play to its technological advantages, continuously increasing the development of high-manganese steel products for ships, and continuously providing personalized material solutions to enhance market competitiveness and brand influence. In order to meet the stringent requirements of customers, Wugang actively forms a joint R&D team with customers and relevant classification societies and research institutes and carries out R&D work in an innovative way to break through a series of technical bottlenecks such as high-manganese steel material performance regulation, welding material R&D matching, and tank forming preparation. During the production process, key technical personnel from the Ministry of Science and Technology and the rolling mill were organized to form an R&D team to clarify key process nodes and points to note, providing support for the smooth launch of the product. In addition, product standards and application guidelines were released, which ultimately achieved the original innovation of the entire industrial chain of high-manganese steel in my country from materials to applications, and completed the first domestic actual ship application.
